The board fits into the chassis, I have the x8version and the board with 11pci slots and both fit. The powersupplies are the one with the larger blades I have the 1280 watt versions. I am not at home so I can't give you a part number.I don't believe that the x9drg-qf will fit into the previous model case. My reading said people were annoyed about that. I will confirm .
